Yes, it depends if you want your crew electrocuted, or not.

Can you explain how the 2-pole, 2-wire waterproof AC connectors suggested by GordMay are going to electrocute your crew if used for 12v DC (assuming they are wired and fused appropriately)?

Re: Faulty 12 volt power point socket Fire put out with a jar of olives in Brine

A little clarification here if you would... are you saying there is something mechanically / electrically dangerous about using AC plugs for DC work, or are you just referring to the fact that there is potential for mixing up what is AC and what is DC (and therefore plugging your DC appliance into an AC socket or vice versa).

Thanks.

Re: Faulty 12 volt power point socket Fire put out with a jar of olives in Brine

I just had an overheating one, I found that I had to insert the plug just right to make it line up with the ground contact for it not to overheat and also there is a contact on the ground that I bent in a little to hold the plug better, this is on a cigarette lighter socket not a power polnt which I think are junk, cigarette sockets are deigned for more heat I think.

This.

Just say no to doing dangerous substitutions.

Re: Faulty 12 volt power point socket Fire put out with a jar of olives in Brine

Cig lighter plugs/sockets are a horrible design. If they don't have a complete ground ring, you need to get the grounds lined up. The plugs fall out (unless you're using the magic locking ones). They overheat. Current capacity is not a standard. They out and out suck.

I used a MARINCO ConnectPro Trolling Motor Plug & Receptacle | West Marine for my solar install (the panel is removable) - Not much bigger than a cig lighter but far more robust. (and more $$$)

Sea-Dog and Perko both make devices like this: Sea-Dog Polarized Cable Outlet - 12 Volt - DC Connectors & Plugs - Electrical - Downwind Marine

If you can mistakenly plug in an ML-1 plug wired for 12v (or any other voltage) into a NEMA 5-15 AC receptacle, you are a magician. It's impossible. That's why it's a great alternative as Gord suggests.

Your correct, thanks for the comment, it dawned on me this morning I had made an instillation error. everything wired has a rated fuse, however my error was I was thinking only one side of the fuse equation the male plug side requiring the power and not the female socket power delivery as per my photos.



Still these plugs are promoted as water proof, but none I can find are fire proof as well.

Thanks but I do not want to cut into the bulk head, my error was to rely on the fuse for the male plug in item and not the the female socket.

Thanks for your question, I'm using the 12 volt socket mostly to run a very small powered pump to move rain water from my porta boat dingy into my boats water tanks which sits on the fordeck, saves me going to the marina using town water.

Frankly I discovered that cigarette sockets are not heat or fire proof that is the problem when one experences a short, like I did.

Actually the problem was the dangerous installation.
